Start with a four-part inspection
- Watch the door move slowly and note exactly where it rubs, catches or makes noise.
- Compare the gaps at the head and sides without assuming an uneven gap has only one cause.
- Look for loose or damaged hardware, worn seals and changes at the floor.
- Record when the problem began, including painting, new flooring, weather or an impact.
Photograph both sides, the hinges, the latch and the worn area. If the door cannot close and secure, or a damaged component makes it unstable, arrange prompt repair before continuing normal use.
1. Squeaky hinges
Listen to identify the hinge or contact point. Check for obvious looseness, rubbing or debris before choosing a lubricant. A squeak is not proof that the entire door needs replacement.
Use only the lubricant and application method specified for that hardware. Do not coat all moving parts with household oil or remove hinge pins while leaving a heavy leaf unsupported. If the noise persists or the hinge is worn, have its condition and alignment assessed.
The squeaky door guide takes a closer look at this symptom.
2. The door scrapes the floor
First remove a loose rug or object from the swing path and check whether new flooring changed the clearance. Then inspect hinge attachment and the frame’s alignment. A scrape near one corner calls for a different investigation than rubbing across the whole bottom edge.
If an accessible hinge screw is visibly loose, use the correct driver and the hardware instructions to snug it without stripping the hole or distorting the hinge. If the screw will not hold, the attachment needs a suitable repair; repeatedly tightening it will not restore missing support.
Do not plane the bottom simply because it touches the floor. Check the permitted trimming allowance, door construction and any label or rating first. Glass, metal, engineered and hollow-core doors have different limits.
3. A screen or storm door sags
Look at the door’s own hinges, frame joints, closer and attachment to the opening. A lightweight wood screen door and a factory-made metal storm door should not receive the same repair by default.
A brace or turnbuckle can be appropriate for some wood screen-door designs, but it is not a universal storm-door fix. Use the maker’s replacement and adjustment instructions for the model. Recheck the latch and closer after the alignment is corrected.
4. The door will not latch or close
Work out whether the leaf reaches the closed position or binds before it gets there. Check for paint buildup, debris, a displaced seal or a latch that does not move freely. Observe where the latch meets the strike.
Correct a sagging leaf or distorted frame before relocating the strike to match it. Enlarging the strike opening can hide the symptom without solving the alignment issue. Use a specified strike adjustment only after the cause is understood.
The door latch troubleshooting guide covers this problem in more detail.
5. The door sticks or is stuck closed
Look for a recent change such as wet weather, a fresh coat of paint, a new seal or a damaged lock. If the door opens, identify the contact area and inspect both the panel and frame. If it cannot be opened normally, get help with the stuck assembly rather than forcing the handle or prying against glass.
Do not drive extra screws into a jamb to pull it away from a swollen or misaligned leaf without checking the frame detail. That can distort the frame and change the seal or latch fit.
Start with the sticking door guide when this is the main symptom. A new problem affecting several doors or accompanied by wall cracks deserves a broader assessment of the opening.
6. The door or frame has physical damage
| Condition | What to assess |
|---|---|
| Scuffed paint or worn finish | Whether the surface can be prepared and recoated with a compatible system. |
| A small hole in a hollow-core face | Whether a cosmetic repair is suitable for the leaf and its use. |
| A split at a hinge or strike | The strength of the attachment and the surrounding material. |
| Soft or decayed wood | The extent of damage and the source of moisture. |
| Broken or loose glass | The correct replacement glazing and safe handling method. |
| Bent metal or a damaged labeled door | Whether an approved repair can preserve the assembly’s required performance. |
Our door hole repair guide covers cosmetic panel damage. Filling a hole or crack does not restore the strength of a failed frame, hinge attachment or security component.
For steel doors and frames, the Steel Door Institute calls for inspecting hinges, locks, glass, seals and finishes. Its guidance reinforces the need to inspect the assembly rather than treating every fault as a surface repair.

Before sanding, cutting or refinishing
Check the manufacturer’s limits and any labels before changing a door’s edges, hardware cutouts or components. A repair that looks tidy can still affect the way an assembly was designed to work. Have labeled fire-door work assessed by someone qualified for that assembly.
In an older home, establish whether the finish contains lead before disturbing it. EPA explains that renovation work on lead-painted surfaces can create hazardous dust and recommends lead-safe practices and qualified help.

For a suitable wood surface, use the wood door staining guide alongside the coating maker’s instructions.
Repair or replace: compare the complete job
| Repair may make sense when | Replacement may make sense when |
|---|---|
| The fault is limited and the door is otherwise suitable. | Damage is extensive or an approved repair is unavailable. |
| Parts and compatible finishes are available. | The leaf or frame no longer meets the project’s needs. |
| The cause can be corrected without repeated work. | Earlier repairs have not addressed an ongoing problem. |
| The complete repair quote is reasonable for the expected result. | Replacement provides a better fit after all costs are compared. |
Ask for an itemized estimate. Include diagnosis, parts, finish work, labor, disposal and any repair to the opening. A replacement quote should include the same surrounding work, plus locks, glazing, shipping and installation where applicable. A slab price and an installed entry price are different comparisons.
If replacement is the right choice, compare interior doors or front entry doors for the intended location. A prehung door still needs accurate fitting and attachment; it does not remove the need for installation skills.
Questions worth asking before you choose
How much does door repair cost?
The cause, materials, access and finish work determine the price. Get a local estimate that identifies the fault and the proposed repair. A fixed online allowance can miss damaged framing, specialty hardware or the need to correct a leak.
Should I trim a sticking door?
Only after checking the cause and confirming that the specific door permits it. Loose attachment, a bowed jamb, new flooring or a displaced seal can create rubbing without requiring a smaller door.
Can I keep the old door and replace the frame?
Sometimes. The leaf must still suit the new frame’s size, hinge preparation, latch, seals and intended use. Have the installer check those details before ordering a frame around the old slab dimensions alone.
